BOND-VTIRE SUPPORT.

Application filed July 30, 1919.

To all whom it may 00/1061 71 Be it known that I, EDWARD A. EVERETT, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bond-Wire Supports, of which the following is a specification.

This invention relates to rail bonding such as is used to provide the electrical conductivity of rail joints and it relates more particularly to a means for supporting the conductors used in such rail bonds, and has for an object providing an inexpensive and rigid means for supporting rail bonds that may be readily applied or removed without interfering with the track construction. These objects are obtained by the construction illustrated in the accompanying drawings in which, Figure 1 is a section of a rail joint showing the bond wire support in place, Fig. 2 is a side elevation showing the application of this invention, Figs. 3 and 4 show two forms of the bond wire support and Fig. 5 is a cross-section of the support.

In order to provide electrical conductivity in a track circuit it is necessary to bond the rail joint. This is most frequently done by drilling a hole in each end of the rail and bridging the joint by one or more conductors, called bond wires. The objects of the present invention are to provide protection and support for these bond wires. In Fig. 1, 11 indicates the rail, 12 and 13 are the fish plates of the rail joint secured by the bolts 15 and 16, Fig. 2. 17 and 18 indicate bond wires secured in holes drilled in the web of the rail outside of the fish plates. One or more bond wires are used as desired. These bond wires, it will be noted are comparatively small and of considerable length and if unsupported between the ends can be readily misplaced with the possibility of engaging the wheels of a passing car or conflicting with the bolts of the fish plates. The

.support provided by this invention rigidly supports the bond Wires and guards against misplacement.

The support consists of a D section or half round strip similar to Fig. 5 and bent as shown in Figs. 3 or 4 to take the contour of the fish plate as indicated in Fig. 1. The end of this strip is bent into an eye 21, formed to rest on the shoulder of the fish plate. This eye has an opening 23 through Specification of Letters Patent.

which the bond wires can pass and which may be closed by a hammer blow at 22 to secure the bond wires in the eye. A hori Zontal leg 1 1- of the protector passes below the rail as shown and is turned over with the hammer at the opposite side as indicated at 25 thus securely clamping the protector in place. Considerable advantage is secured in the use of a D-section or half round strip for this support as it provides a fiat surface to engage the rail joint and a round surface to engage the bond wires thus permitting of the utmost freedom for vibration of these wires without danger of chafing. This section provides considerable rigidity that cannot be bent without the use of tools and cannot therefore be easily tampered with and the rounded outer surface offers little obstruction on the joint.

In certain cases it may be desirable to place the bond wires at the bend of the fish plate 2 1, Fig. 1. For this construction the support is shaped as shown in Fig. 4: with the eye located at this bend and applied to the joint similar to the construction shown in Fig. 4e. One support is indicated in Fig. 2 in the center of the oint, however, any number desired may be applied to a joint as the conditions require.

This support may be applied to a joint before the bond wires are installed and clamped in position. The bond wires can then be threaded through the eye or through the opening 28 before this opening is closed. This support can also be applied after the bond wires are in place, these wires being simply sprung out to enter the opening 23 of the eye.

Having thus described my invention, I claim:

1. In combination, a rail joint, bond wires for said joint, a support for said bond wires, consisting of a strip of half-round section, the flat side of said strip placed adjacent said rail joint and conforming to the contour thereof and an eye turned on the end of said strip with the half-round section on its inner curve, said eye inclosing said bond wires.

2. In combination, a rail joint, bond wires for said joint, a support for said bond wires consisting of a strip of half-round section, the fiat side of said strip placed adjacent and bent around said joint, an eye turned outward on the end of said strip, said eye inclosing said bond wires.-

8. In combination, a rail joint, bond wires inclosing said bond wires and capable of for said joint, (1 support for said bond Wires being closed when said bond Wires are in consisting of a comparatively rigid strip of place. v l0 half-round section, the flat side of said strip Signed at New York, in the county of V 5 placed adjacent said rail joint and conform- New York and State of New York, this 24th ing to the contour thereof, a partially closed day of July, A. 111919; 7 eye on the upper end of said strip, said eye EDWARD A.
